Problems solved by technology

Due to the complex mechanical operations associated with the vapor compression cycle, the system response to varied demand is typically slow.
However, a known problem in the art is that the one or more thermoelectric devices generate a magnetic field.
This magnetic field is known

Embodiment Construction

[0026]Referring to FIG. 1, there is shown a cross sectional view of a thermoelectric element shown as reference numeral 10. The thermo-electric element or device 10 is preferably a solid state device. The device 10 has a first P type semiconductor 12 and a second N type semiconductor 14 with an electron as a charge carrier. Current from a power supply is passed through the N type semiconductor 14 to the P type semiconductor 12.

[0027]When current passes therethrough as indicated by reference arrow 16, heat is removed from surface 20 and transferred through the thermoelectric device 10, and then deposited to a second surface 18 of the thermoelectric device as indicated by arrow 22. The heat removal from the surface 20 causes the absorption of heat from the adjacent environment through a working fluid in contact with the cold surface 20. Likewise, the heat generated at surface 18 is ejected through a heat transfer medium. This thermoelectric device 10 is well known and is understood by...

Abstract

A refrigeration system has a compartment and a first cooling device. The first cooling device cools the compartment and generates a magnetic field. The refrigeration system also has a second device. The second device uses the generated magnetic field for additional cooling to the compartment.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a temperature control for a compartment. More particularly, the present invention relates to a magnetic refrigeration system that uses a magnetic field generated from a number of thermoelectric elements that are wound in a configuration.[0003]2. Description of the Related Art[0004]Temperature control systems for heating and cooling devices are known in the art. Such known systems use a vapor compression cycle to provide cooling. Typically the refrigerant in vapor phase is pumped from the evaporator by a compressor. The refrigerant is then compressed to a superheated vapor. The high-pressure gaseous refrigerant that absorbs the heat is sent to a condenser. The refrigerant vapor is condensed to high-pressure liquid by transferring heat from the refrigerant to a heat sink that has lower temperature. The condensed refrigerant liquid is circulated to a throttling valve. The throttling valve r...
